Abstract
The present invention relates to a process for dyeing or printing organic material, which comprises applying at last one dye selected from those containing a chromophore radical from the monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, nitroaryl, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, naphthoquinone, pyrenequinone or perylenetetracarbamide series which contains an acrylamide, methacrylamide, bromoacrylamide or chloroacrylamide reactive group, at least one colourless cationic compound containing at least one polymerizable double bond, and at least one polymerization initiator and then subjecting it to thermofixation. Further auxiliaries to the organic material may optionally may optionally be included.
